vRA Network profile IP Usage monitoring

I got question about VMware vRealize Automation (vRA/vCAC) network profiles usage details or monitoring/notifications that how can we monitor Network profiles, how much IPs are configured, consumed, available etc. Unfortunately there is no direct method you can do all these things also there are no notifications which you can configure.

After some research i have to decide to build something with vRO (vCO) that will do monitoring. I am using vRA 7 with embedded vRO (7). Below solution might not be the best and there is always scope for improvement, but it is doing what is supposed to do. I came across very great blog from Jonathan Medd which talks about using vRA as REST host.

Requirements:

1. Monitoring all network profiles in vRA for their usage
2. Allow configuring threshold – in this case how many IPs should always be available
3. If network profile usage is more than threshold should send email notification
4. Should not require manual intervention (scheduled)

vRA 7– Allocating resources to Business Group – Reservations and Reservation policies

 

In vRealize Automation VMs can only be deployed on reservations. Now before business groups can provision VMs, fabric administrator has to create one or multiple reservations and assign to business group. There is also one more component called Reservations policies, you can compare them to vSphere tags, they allow you to categorize and group multiple reservations. For example if you have more than 1 gold tier reservation, you can created single Gold Tier reservation policy and assign it to all your Gold Tier reservations.
